Um. Yeah.
Forgive me if I’m rather less than impressed with Protestant facility in the Greek language. You guys are still trying to push the “big stone, little pebble” canard for Matt 16:18 despite some of your own best scholars likening that interpretation to a foreigner inferring “butterflies” are somehow related to dairy products.
In Matthew 16 Jesus is talking to all of the Apostles. They were all asked the question of who they thought He was. Though Peter was the one who answered for the group Jesus was talking to them all. When Peter said that they believed He was “Christ the Son of the Living God” Jesus replied and said that it was not flesh and blood that had revealed that to Peter but that it was “my Father which is in heaven”. He then says to Peter “and thou art Peter”, acknowledging that He knew who Peter was just as Peter knew who Jesus was. Then Jesus, referring back to “my Father which is in heaven”, says, “upon this rock I will build my church”.
In other places in scripture Jesus is referred to as the “corner stone”, but the rock that the church is build on is the Father.
If you want reference to God as the Rock here are some verses.
Deut. 32:4 He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.
2 Sam. 22:2 And he said, The LORD is my rock, and my fortress, and my deliverer; 3 The God of my rock; in him will I trust: he is my shield, and the horn of my salvation, my high tower, and my refuge, my saviour; thou savest me from violence.
Psalm 18:31, "And who is a rock, except our God."
Isaiah 44:8, "Is there any God besides Me, or is there any other Rock? I know of none."
Rom. 9:33, "Behold, I lay in Zion a stone of stumbling and a rock of offense, and he who believes in Him will not be disappointed."
1 Cor. 3:11, "For no man can lay a foundation other than the one which is laid, which is Jesus Christ,"
1 Cor. 10:4, "and all drank the same spiritual drink, for they were drinking from a spiritual rock (petras) which followed them; and the rock (petra) was Christ."
1 Pet. 2:8, speaking of Jesus says that he is "A stone of stumbling and a rock (petra) of offense"; for they stumble because they are disobedient to the word, and to this doom they were also appointed."
Makes one wonder when it was that the RCC decided that God was no longer the “Rock” doesn’t it?
